If I could only find the exact handle material...
I hope that NASA wasn't the only one who was using that specific G-3.
Well, we all know Capt. is the king of handle material in his "stash", particularly this jade G3 stuff.
However, I've seen Gary Clinton list a couple of Model 10s with material that looks just like the jade that was used on the MM. He may only have (or had) material for slabs, but worth a phone call or e-mail to ask.
If you think that jade looks good in pictures, wait till you see it outside in the sunlight
